Bronstein's Dove Tail Mate




David Ionovich Bronstein 1924 - 2006
Russian Chess Grandmaster, Author and Artist.

A great chess player has passed away.
An artist of the chessboard who loved chess.

I've been asked by another site to do an obituary/tribute
and as they pay rather well (incredibly well) I feel I would
be doing them an injustice by repeating any of it here.
I'll put on a link on when I've polished up the piece.

I will however give you one of his games. The finish
is relevant to some parts of this piece.

D.Bronstein - H.Hunt, Maidstone Menchik Open, 1994.

D.Bronstein - H.Hunt

1.e4 c6 2.d4 d5 3.f3 e6 4.Nc3 Bb4 5.Nge2 dxe4 6.fxe4 Qh4+ 7.Ng3 Nf6 8.e5 Ne4 9.Qd3 Nxg3 10.Qxg3 Qxd4 11.Qxg7 Bxc3+ 12.bxc3 Qxc3+ 13.Kf2 Rf8 14.Bh6 Nd7 15.Bd3 f6 16.Rae1 b6 17.Qxh7 Qd4+ 18.Kg3 Nxe5 19.Rxe5 Qxe5+ 20.Bf4 Qc3 21.Kh4 f5 22.Be2 Qf6+ 23.Kh3 Rf7 24.Bh5 Ke7 25.Bxf7 Qxf7 26.Bd6+ Kf6 27.Qh6+ Qg6 28.Be7+ Kf7 29.Qf8


Harriet Hunt actually resigned on move 28. I played on
because I want to talk about the final mating pattern.

In issue 206 of Scottish Chess, Keith Ruxton in his section
called 'Smashing the Glass Ceiling' gives this position.


Keith emphasis the use of building blocks
(mating & tactical patterns) and states most
players will spot the combination of moves here.

1.Nf7+ Kg8 2.Nh6++ Kh8 3.Qg8+ Rxg8 4.Nf7 mate.

Then adds seeing it does not mean you are a
chess genius. you are simply recalling a
pattern we have all seen many times before.
This is Philidor's Legacy.

"It's like arithmetic:
we may have to calculate 31x16
but we do not have to calculate 3x3:
We know the answer already."

You must know as many typical tactical patterns and ideas as possible.

So regular readers will now be thinking...

"...someone, somewhere has missed a Philidor's Legacy..."

Yup!

"...they are now going to become infamous..."

Yup!

"...they are going to be named on the world wide web..."

"Yup!"

"...and for the rest of their miserable lives people are
going to point at them in crowded places...
...there is the guy who missed Philidor's Legacy..."

Yup!

In this position white played QxN.



Ok you can tell by the fact Black should have resigned it was
from a junior game. So I shall refrain from naming the poor wee soul.
(leave 10,000 in used notes behind the bar in Bells).

I'll add here that if 1.QxN was not in the position then
I bet the youngster would have found the mating idea.

Check all checks. Even the silly looking checks.
Whilst looking it may trigger a response from your memory cells.
But first you have to place the pattern there to recall it.

You must know as many typical tactical patterns and ideas as possible.

Right try this:
White to play and mate in 4. Give it 30 seconds.



It's a wee bit tough but solvable. here is a clue.



This is the fairly standard mating pattern we are after.
Now try it again. This pattern is used in the final mate.
This time stay with it till you have the mate.
(Note you do not need the Bishop and Knight so sac 'em).


solution at bottom.

In the Bronstein game, white used a 'Dovetail Mate.'
Here is another example. White plays 1.Qg8 mate.



The flight squares f6 & h6 are blocked or can be covered.
Note how strong the Queen is checking right next to the
King in this manner. The Queen herself covers 5 escape squares.
Take off the Rook and Pawn and put a White pawn on g5.
It's still mate.

Here is a Dovetail Mate missed by Alan Tate v T.Matko, Edinburgh 2006.



Alan missed 42 Rxe6+! Kxe6 43 Qe5 mate (though he still won).

Kin to the 'Dovetail' is the 'Epaulet Mate.'
Here it is in it's most brutish form.



The blocking pieces sit on the King's shoulders.
Here is the same mating pattern in a more familiar setting.



That's quite enough of that stuff for today.
Here is an Edinburgh League game which features
a dovetail mate just like the Bronstein game.

J.Adamson - J.Mowat, Edinburgh Chess League, 2006
An interesting tussle this.
White accepts an IQP and knows the rules. IQP = Attack the King.
Black is defending OK when suddenly we have an opposite coloured
Bishop attack. White hits g7. Black hits g2.
Note White's Bishop tour. c1-e3-d2-xh6-g5-e7-b4-c3.
Finally on c3 it supports a Rook on going to e5
giving us this position with Black to play:



Black chose 28...Qg6?

Better was 28...Qf6 29.Rg5 Rxc3 30.bxc3 Qxc3 Black is
suddenly active and there is a wee mate in there:
31.Re1 Rd2 32.Rh5 Rxg2+ 33.Kxg2 Qxf3+ 34.Kg1 Qg2 mate.
33.Kh1 stops the mate but after 33...f6 Black's winning.

White played 29.Rh5 But 29.Rg5! first.
29...Qh6 (forced as 29..Qd3 30 Rxg7+ Kf8 31.Rg8!+ mates)
and then 30.Rh5 wins the Queen.

After missing this chance the game looked like it
was going to get bogged down with some heavy piece play.
White appears to have run out of ideas. (32.a3)
Black took this as a signal to get active.

So Black moved his Rooks off the back rank.
This gave White fresh ideas and moved Rook and Queen into
the rear of the Black King. A Dovetail Mate on f8 can only
be stopped by Black shedding a piece (35..Bc8) so 1-0.

J.Adamson - J.Mowat

1.e4 c5 2.Nf3 d6 3.Bc4 Nc6 4.c3 e6 5.d4 cxd4 6.cxd4 d5 7.Bd3 dxe4 8.Bxe4 Nf6 9.Nc3 Nxe4 10.Nxe4 h6 11.0-0 Be7 12.Be3 0-0 13.Qe2 Nb4 14.Ne5 Nd5 15.Bd2 b6 16.Qg4 Nf6 17.Nxf6+ Bxf6 18.Bxh6 Bb7 19.Rfd1 Qd5 20.f3 Kh7 21.Bg5 Bxe5 22.Qh4+ Kg8 23.dxe5 Qxe5 24.Be7 Rfe8 25.Re1 Qf5 26.Bb4 Rac8 27.Bc3 Red8 28.Re5 Qg6 [28...Qf6 29.Rg5 Rxc3 30.bxc3 Qxc3] 29.Rh5 f6 30.Qh3 Kf7 31.Re1 Rc6 32.a3 Rd3 33.Rh8 a5 34.Rb8 Ba6 35.Qh8


Look at the final position:
36...e5 then 37.Qe8 mate.
36...Q any then 37.Qe8 mate.
36...Ke7 37.Qf8+ Kd7 38.Qd8 a perfect Dovetail Mate.


solution to mating pattern puzzle:
1.Bg7+ Rxg7 2.Qf8+ Rg8 3.Ng6+ hxg6 4.Qh6 mate.
